Also before you ask, I actually had this planned out a long time ago, I just forgot to add this in and these schools do impact the story a lot and goes in deeply into the entire story of the battling 101 itself.
Again, optional to read as this is literally one gigantic info dump.
Also these people are battle crazy holy crap and despite having specified schools for beating the living crap out of each other like its a fighting game that is on steroids where people bring swords to dog fights and actually win...These guys actually still learn something so they aren't battle-hungry barbarians that turn into badasses one way or another...well most of them.
Before going into school related stuff, there is some things to know. Besides the regular schools, there are 8 major combat schools around the world. One of which is BOC Academy. Which is in America.
BOC Academy: The fighting academy where one can easily obtain high learning in certain fields of fighting in such things like swordsmanship, marksmanship, or demolitions. Though this place is known for its efficiency, there is always its reputation of being surprisingly wild which these people would go on war with each other which they end up creating a WWIII simulator. Though, this is surprisingly good for teaching combat as they always get a hands-on example of their certain field, of course they are mostly using wooden blades, blanks, rubber bullets, and other things...MOSTLY.
Summary: In terms of an RPG, this academy pretty much assesses you with giving you a class or title of your character and then you either leave the school becoming whatever you desire (Although these guys enforce the living crap out of morals and all things good) You can go to one of the 7 schools.
The 7 schools refer to the 7 best specialized combat academies in the world in which each specializes in certain fields where you advance your abilities even further. Although you do not have to attend BOC academy, it would be recommended.
Highland castle: The highland castle is a academy that is in the Scottish highlands which this is a medieval-style academy which they actually do have proper plumbing and technology so you don't have to worry about that. The specialization in the highlands is essentially blade and shield specialty which gun-blades and gun shields are most definitely enforced here. The size of the highland castle is quite large and although medieval, this is one place that you should not screw with because these guys have some big cannons that are absolutely ridiculous.
Desert Bunker: An underground academy in Australia which this place specializes in thermal, desert tactics and survival, scavenging/ Juryrigging, unarmed, and explosives. The desert bunker is a giant series of bunkers connected together through a complex and intricate design of passageways and other things. By the way, it's not claustrophobic in there. This place you shouldn't screw with in the first place mainly because this continent already has about 75% of its indigenous animals that can potentially kill them and the fact that these guys are in Australia.
Sea Fort: A specially made academy that not only reaches above water, but also connects underwater to the sea ground. This is pretty much close to Antarctica and these people are trained specifically to naval, underwater, and tactical warfare. So essentially, all of these people are mainly a support group, but a quite deadly one at that. One main reason for not fighting these people is the fact that these guys know how to defend their position and will demolish you no matter what the heck you bring (Unless its a nuclear bomb) Also, these guys are also known for research and development which is all confidential under the sea floor.
Flying Domain: As it says, it is pretty much a flying island which is only up using some high-end, anti-gravity technology. These people are essentially specialists in, of course, flying tactics, although it may seem simple, these guys are pretty much trained to excel in dog-fights, hit-and-run tactics, search-and-rescue missions, quick evacuations and other things. So basically its another support group, and one that you do not want to fight their army with as they have some big flying death machines. Also this is somewhere above Europe
Frozen Bastion: Essentially it was originally a giant fortification that was transformed into a combat academy...which this is in Russia. The Frozen Bastion specializes in winter tactics, guns, artillery, and defensive tactics. The only thing I have to say is that these guys are tough, intimidating, and will make you feel the wrath of mother Russia.
Underground Citadel: A giant underground citadel under south-America , which these people are specialists in stealth, assassination, deception, secrecy, pretty much all behind-the-scene, cloak and dagger stuff. One main reason why you shouldn't mess with these people is that they have eyes and ears everywhere and they can kill you in your sleep.
Dragon Temple: In technical terms, this thing actually has 5 branches: Vietnam, China, Japan, korea, and India. But all of them pretty much are the same thing, which all of them specializes in the supernatural, so basically expect people to have some mystical power or be insanely powerful. The fact that the name is dragon temple and where the dragon temple is even at...Yeah that is not going to be good.
Regular schools: They are regular schools which this is basically pointing towards high school...for the most part.
With all of these in mind, you actually can actually just make a comedic school moment without the need of adding characters from the 101 or any stuff. Just add people in and let the good times role.
